Detailed description of the invention
The copper tuning Self-locking screw of the present embodiment removes the centrifugal grinding technics of grooving inner burr, is the Transformatin that the copper tuning Self-locking screw that is M4 to size specification carries out grooving inner burr, and its concrete technology step comprises:
Step 1: on the centrifugal grinder that is XML-30 a model, take off 4 planet drums, successively toward the Self-locking screw that packs 2.5 ± 0.1 KG in each drum into, select the oblique triangular prism that is shaped as of 4*4(oblique triangle whiteware abrasive material, previous digital 4 represent that the bottom side length of triangular prism is 4 mm, a rear numeral 4 represent the incline of triangular prism long be 4mm) oblique triangle whiteware abrasive material, be that 2:1 joins in cylinder according to the volume ratio of abrasive material and part;
Step 2: add each 50 ± 2 mL of grinding agent and cleaning agent, then add running water, amount of water is just to flood added material be advisable (note added all material total amounts and drum upper end stay 2-3 centimetre space);
Step 3: 4 drums are loaded onto on centrifugal grinder successively, are 240 ± 5 seconds according to the selected milling time of specification size M4 of Self-locking screw, start to grind until grind end.
Step 4: after machine stops, taking off cylinder, clean, separate workpiece and abrasive material.
The preparation technology of a kind of tuning Self-locking screw of the present invention, especially a kind of copper tuning Self-locking screw goes the centrifugal grinding new technology of grooving inner burr, effectively removed the burr producing in Self-locking screw grooving after slot-cutting machine processing, also the polished rod part surface of screw has been carried out to polishing, ensured the requirement on machining accuracy of Self-locking screw, simultaneous grinding efficiency is high.
In above-mentioned technique of the present invention, the whiteware abrasive material of employing has the performance of high rigidity and high abrasion, and in process of lapping, can not produce chip and stop up grooving, and thin (granularity is 350 orders) of its particle, for fine gtinding, deburring has good effect.A certain proportion of Self-locking screw and whiteware abrasive material are placed in cylinder, in drum rotation process, the corner angle that oblique triangle whiteware abrasive material is sharp contact with grooving and produce grinding, thereby the burr in removal grooving, add and control milling time well, just can remove efficiently the burr in Self-locking screw grooving, and can not produce high temperature, can not form residual stress and strain layer and part of damage after processing.
The contrast test explanation of abrasive material and volume of part proportioning: taking the screw of M4 as example, if abrasive material is less than 1.8:1 with volume of part ratio, while grinding, screw is not to be evenly distributed between abrasive material, and exists screw to contact and mutually push and rub with screw, the surface quality of broken parts part; If abrasive material is greater than 2:1 with volume of part ratio, the result of grinding also can reach requirement, but each screw amount minimizing of grinding, Efficiency Decreasing.
The contrast test explanation of abrasive material size: the size of abrasive material is to select according to the size of the size of Self-locking screw, grooving.Taking the screw of M4 as example, if the abrasive material that is greater than 4*4(test and selected 5*5 or 6*6 of abrasive material choosing), in centrifugal process of lapping due to the effect of centrifugal force, the mutual pressure between abrasive material and screw increases, grinding cutting amount is excessive, easily injuring part surface; If if the abrasive material that is less than 4*4(test and selected 3*3 of abrasive material choosing), in centrifugal process of lapping due to the effect of centrifugal force, the mutual pressure between abrasive material and screw reduces, grinding cutting amount is too little, can not well burr be removed clean.
The contrast test explanation of milling time: milling time is to select according to requirement on machining accuracy.Taking the screw of M4 as example, if milling time exceedes 240 ± 5 seconds (milling time of 250 seconds, 260 seconds, 270 seconds was selected in test), occur abrasive material to the cutting output of screw excessive and loss surface quality of workpieces, or there is grinding out higher precision and be not used, waste efficiency; If milling time less than 240 ± 5 seconds (milling time of 230 seconds, 220 seconds, 210 seconds was selected in test), occurs that abrasive material does not reach the Grinding Quality of expection not to the burr cutting output of screw.
